Type
data
:

(Vog.) Koehne (Leguminosae)
, Baotianman, Neixiang County, Henan Province, P.R.

Paratypes
,
11 females
and
2 males
, with the same data as
holotype
.
Relation to host
: Vagrant on leaf surface. No damage to the host was observed.
Etymology
: Derived from the specific epithet of the
type
host plant,
formosa
.
Note
: This species is similar to
Tetra shiheziensis
Wang & Lu, 2004
, but can be differentiated by the prodorsal shield with complete median line, empodium 7rayed, solenidion tapered and dorsal annuli with spiny microtubercles.
